Information service system

ABSTRACT

Information service system with application devices, particularly for the police, with information systems, an intelligent, dynamically implemented portal for a standardized access to the downstream information systems with a scope dependent on the user, at least one terminal for access to the portal and at least one communication device for linking the terminal with the portal.

[0001] The present invention relates to an information service system, particularly for the police.

[0002] Despite excellent overall conditions, the police in Germany and also in other countries is exposed to modern challenges, which are becoming increasingly difficult to handle using conventional means.

[0003] These challenges include

[0004] internal factors, such as restructuring within police organizations and an increasing cost pressure and

[0005] external factors, such as an increase in complex criminal forms, e.g. business crime or organized crime and ever larger geographical police areas (Germany, Europe) and an associated increase in crossborder crime.

[0006] Such challenges can only be handled if the police is placed in a position to do so. The necessary access to relevant information only exists in fragmentary form, i.e. the police organizations of the 16 Federal German states, the German criminal investigation office, the German border police and the customs administration, which in part also handles police problems, are unable to access information to an extent adequate for dealing with a particular task.

[0007] Therefore the problem of the invention is to provide an information service system enabling a user, independently of the access channel available, to access in simple manner the instruments required by him, such as information and applications.

[0008] According to the invention this problem is solved by an information service system with application devices, particularly for the police, with information systems, an intelligent, dynamically implemented portal for standardized access to the downstream information systems with a scope dependent on the user, at least one terminal for access to the portal and at least one communication device for linking the terminal with the portal. The term intelligent portal is understood to mean a portal which also makes available its own functions. The term dynamically implemented portal is understood to mean a portal generated as a function of the context (e.g. date, time of day, special events, notified user, etc.). The counterpart is a static portal, which although regularly “filled” with new information, provides no flexible, context-dependent display.

[0009] The information systems can also incorporate an external and/or at least a local data bank. This can e.g. be a data bank of a private or public organization.

[0010] Advantageously the information systems incorporate at least one local media data bank.

[0011] It is also possible for the information systems to incorporate at least one local data warehouse, which is a data store, e.g. for image or video data.

[0012] Advantageously the information systems incorporate at least one local device for an application. For example, the application can be used for use planning.

[0013] According to another special embodiment, the information systems incorporate at least one local office communication system. For example, the office communication system can be used for detecting, processing, sending and administering documents and for receiving, producing, sending and documenting E-mails.

[0014] The portal can also incorporate a server.

[0015] Advantageously the portal incorporates an engine layer with at least one engine on a layer with an administration device for administering users, the configuration of engines and the administration of upstream and downstream layers. The engines are machines for fulfilling certain portal tasks.

[0016] In an upstream layer, the portal preferably incorporates a device for authenticating a user and the server. It is a hardware layer which is used for establishing who is communicating with whom.

[0017] The authenticating device advantageously also incorporates a user identifying device.

[0018] In an upstream layer, the portal advantageously incorporates an authorization control and storage device for regulating the extent of access of a user. The authorization control can take place via user and user group rights.

[0019] Advantageously the portal has a device for displaying use possibilities of the portal as a function of the external context, such as e.g. date, time of day, user and special events.

[0020] According to another special embodiment of the invention, the portal in the upstream layer can incorporate a device for encrypting the data transmitted via the communication device and for decrypting the data received via the communication device. Such a device is used to protect sensitive data pollable via the information service system against unauthorized interception.

[0021] Advantageously the portal also incorporates a device for providing or establishing the integrity of the data transmitted and received via the communication device. This is intended to prevent or prove an inadmissible manipulation of the transmitted data.

[0022] According to another special embodiment of the invention, the engine layer incorporates a subscription engine for subscribing to information, lists and further services through a user. Thus, a user can inform the information service system of his interests (active personalization) and receives innovations in said fields of interest, e.g. after logging in.

[0023] The engine layer advantageously incorporates a filter engine. The filter engine can investigate on the basis of predetermined criteria different information areas for the particular user. Thus, as soon as a user carries out a personal, factual or other type of poll or interrogation, the filter engine accesses its known information sources and compiles a list from all the search results.

[0024] It can also be provided that the engine layer incorporates an information repository engine and/or an application repository engine and/or office communication repository engine. The information repository engine can contain a metadata structure of the downstream information systems and path information for access to the same. The information repository engine is used by services for which the storage location is not relevant, but the type of information (fact, person, etc.) is. Thus, e.g. personal information is stored in different information systems, such as provincial and national criminal investigation offices and Interpol. Instead of supplying the information to all these services, whose information systems contain personal information, it is sufficient on the basis of the “person” inquiry to determine all the necessary storage locations via the information repository engine. An application repository engine contains a list of applications made available to the users of the information service system via the portal in the downstream information systems. Besides the location of the application, it also contains an information on user and user group rights necessary for access. If e.g. access is to INPOL through a police officer, then this access is admissible as a result of his user group membership and the connection to INPOL is built up. However, if a magistrate wishes to access INPOL, access is refused, because as a result of his user group membership the magistrate does not have an authorization thereto. In the case of an extended power the magistrate can be given INPOL authorization on the user plane and once again access to INPOL is made possible. The office communication repository engine offers standardized access to a local office communication system and its associated functions.

[0025] Advantageously the portal incorporates an output engine by means of which a user is given the possibility to obtain information objects via different access channels and in different formats.

[0026] Advantageously the portal incorporates an interface integrator for downstream information systems. Thus, the portal must assist different interfaces, because in large organizations, such as e.g. the police organization, access to the most varied information systems is necessary. These include, in addition to the different platforms and system architectures, different information sources, data displays and data banks, such as relational and multidimensional data banks and unstructured data memories. This also implements interfaces to the data warehouse and data mining system.

[0027] Preferably the portal incorporates at least one multivalent or value-added service system. The value-added service system offers a specific service and is part of the portal and consequently does not belong to a downstream information system. Each value-added service system controls access authorization itself, i.e. on calling up such a system it checks the same by means of the user profile and the authorizations necessary for the value-added service to establish whether the user or user group rights are adequate for the use of the said service. If authorization is inadequate access to the value-added service is refused.

[0028] The portal advantageously also contains a request broker, which on the basis of the nature of the user enquiry, allocates the same to the correct engine and after running the enquiry ensures that the information obtained is transmitted back to the correct user.

[0029] Another special embodiment according to the invention is characterized by a firewall machine between the portal and the at least one communication device. It serves to implement a firewall and monitors the entire data traffic between the terminals and the portal in order to prevent unauthorized penetration of the information service system, the introduction of virus programs and similar attacks.

[0030] Finally, a special embodiment of the invention is characterized by a firewall machine between the portal and the downstream information systems, which has the same function as the previously described firewall machine, but relative to the portal-downstream information system transition.

[0031] The invention is based on the surprising finding that by means of a standardized access, namely the portal, the available data and application devices of the most varied organizations can be rendered easily accessible and each, e.g. police officer independently of the access channel is able to obtain function-related information and is consequently able to fulfil his task. The portal also allows the linking of information rendered accessible and application devices, so that these can be made an indirect component of the portal. By producing the connection of data from existing information systems and application devices, a new information quality can be created and consequently an added value necessary for the police. The necessary information are displayed in context, so that the police is better able to fulfil its functions and strategic aims can be more logically implemented.

[0032] In addition, the use of a portal, besides the integration of existing information systems and application devices, also permits the identification, implementation and integration of future information systems and application devices. New information systems and application devices after production on the basis of the architecture of the existing information service system, can be made available in a simple, standardized manner and linked with existing information systems. Thus, in those areas where as a result of lack of instruments existing potentials cannot be presently completely exhausted, it is possible for the police to receive assistance. For example, operative controlling, instruments of risk management or training and knowledge applications can be integrated.

[0033] Further advantages and features of the invention can be gathered from the claims and the following description of an embodiment illustrated by the attached drawings, wherein show:

[0034]FIG. 1 Diagrammatically the technical architecture of a special embodiment of an information service system according to the invention.

[0035]FIG. 2 Diagrammatically safety zones resulting from different access authorizations.

[0036]FIG. 3 Diagrammatically the functional systematics of the special embodiment of the information service system of FIG. 1.

[0037]FIG. 4 Diagrammatically a use example.

[0038]FIG. 1 diagrammatically shows the technical architecture of a special embodiment of an information service system according to the present invention. The information service system can be subdivided into three components, namely A: access channels, B: intelligent portal and C: downstream information systems. The access channels are used for producing access to an intelligent, dynamically implemented portal and are implemented by terminals 10 to 16 and communication devices. With regards to the access, a distinction is made between a local access, a location-independent access by means of a mobile PC, location-independent access with terminals capable of transmitting data and location-independent access with terminals unable to transmit data. Thus, any authorized user can alternately use any random access channel.

[0039] With a local access, users have fixed, location-bound operating positions, as represented by terminal 10 in the form of a PC. The communication device for linking the terminal with the portal B incorporates a remote data transmission device 18 in the form of a telephone fixed or mobile radio network, a router 10 (junction computer between data networks) and the Internet and with respect to the latter use is made of web browsers having a HTML basis and standardized TCP/IP networks as the network product. In FIG. 1 a HTTP server 22 represents the Internet and allows a continuous, standardized use of office communication systems.

[0040] A location-independent access with mobile PC's have full-value, but not location-bound operating positions, like the terminal 12 in FIG. 1 in the form of a laptop or notebook. The communication device for linking the terminal 12 with the portal B looks the same as in the case of terminal 10. As compared with a PC located at a fixed location (see terminal 10), a terminal 12 offers the possibility of a user being able to dial into the portal B by means of communication mechanisms in the laptop or notebook and from different locations and can make available the same functions as when using a stationary PC.

[0041] In the case of a location-independent access with terminals capable of transmitting data, such as e.g. the terminal 14, an associated communication device incorporates a remote data transmission device 18 in the form of a mobile radio network, a router 20 and a WAP (Wireless Application Protocol) server 24 with a WAP browser based on WML. Standardized TCP/IP networks are used as the network product.

[0042] Finally, standard mobile radio telephones represent an example for terminals 16 which are not able to transmit data and permit a location-independent access. The associated communication device for a standard mobile radio telephone incorporates a remote data transmission device 26 in the form of a mobile radio network and an IVR (Interactive Voice Response) server 28, i.e. an interactive voice system enabling a user to selectively poll information and also received information in planned form. If the terminal 16 is WAP-capable, the information can also be polled and received by the WML-based WAP server 24.

[0043] In each case a firewall machine 30 or 32 is placed between the access channels A and the portal B and between the portal B and the downstream information system C. The portal B incorporates an application server 34. The downstream information systems C inter alia incorporate an external data bank 36, e.g. INPOL, which is accessible through a router 38 and a WAN (Wide Area Network) 40, a local device 42 for an application, e.g. use planning, a local office communication system 44, a local data warehouse 46 and a printer 48.

[0044] As a result of the sensitivity of the data available through the information service system the security aspect is of great importance. The term security in the context of network-based applications consists of the following elements:

[0045] a) Server and client-side authentication—who is communicating with whom?

[0046] b) Authorization—what access authorization does the enquiring user have?

[0047] c) Data security—can the data transmission be intercepted?

[0048] d) Data integrity—do the data arrive on transmission in the same way as when transmitted?

[0049] It is not possible for any random user to directly access all data available via the portal. Access to the information is fundamentally subdivided into three different security zones (cf. FIG. 2):

[0050] Internet

[0051] All undefined users without authorization to sensitive data and having a guest status can enter this zone. Access is only possible on the static side making available general information via the information service system. The only contact possibility in this security zone consists of an E-mail to the operator of portal B, no content personalization is possible.

[0052] Extranet

[0053] All trusted users 50, 52 of the information service system are able, following authentication, to dial contents. Only part of the users, namely user 52, has the possibility to poll contents. All private and public organizations not belonging to the police can enter the Extranet.

[0054] Intranet

[0055] All internal police users can enter this security zone. Following authentication there is a personalized build-up of portal B. In this security zone there is reading and writing access to all information systems authorized for the user. In order to obtain a high security standard the server and client-side authentication referred to hereinbefore under a) can take place as follows:

[0056] Access Via Terminals Able to Transmit Data

[0057] To ensure that the desired application server 34 is reached by an authorized client (user), the following procedure can be adopted:

[0058] 1. Enquiry via HTTP server 22 or WAP server 24

[0059] 2. Acknowledgement of portal B with certificate, public key (asymmetrical encryption method) and signature

[0060] 3. Client-side production of a session key for the actual connection

[0061] 4. Encrypting the session key with public key of portal B

[0062] 5. Dispatch to application server 34

[0063] 6. Decryption of the session key with a private key of the information service system

[0064] 7. Request to identify the client via symmetrical encryption (session key)

[0065] 8. Identification of the user as a function of the security zone, no identification being necessary if a user belongs to the security zone (Internet), whereas an identification procedure is necessary if a user belongs to the Extranet or Intranet security zones. In the case of a guest access no identification is necessary, whereas with an Extranet access an identification can take place via user names and passwords and with Intranet access the identification can take place in the form of a user name/chipcard in conjunction with a biometric method (fingerprint, voice analysis, iris analysis)

[0066] 9. Granting access after identification in application server 34.

[0067] In the case of access via terminals which cannot transmit data (voice connections), the server and client-side authentication can take place as follows:

[0068] 1. Dialling in via a fixed access number of the information service system

[0069] 2. Inputting the user identification via a telephone keyboard, assuming a MFW-capable telephone

[0070] 3. Additional identification via the voice

[0071] 4. Caller number registration

[0072] The authorization referred to hereinbefore under b) can take place on the application plane within the portal B, i.e. every user has a profile enabling him to access certain functions. Unlike in the case of optimistic control, where access rights are taken away from the user and from the outset has all possibilities, authorization here is pessimistically controlled. Access rights must be expressly allocated to a user.

[0073] The authorization control takes place by means of user and user group rights, at least one user group being associated with each user. Compared with user group rights, user rights have a higher priority. If e.g. a user is not authorized on the basis of a user group membership to use a specific application, as a result of widened powers he can be personally given this authorization and in this case authorization applies on the user plane.

[0074] Authorization storage takes place as a function of the security zone:

[0075] Internet

[0076] The user only has guest access and cannot dial any applications. The storage of the access rights takes place in a data bank as a “guest” profile of the “guest” user group.

[0077] Extranet

[0078] The user has a personalized access, i.e. he must make an application in the information service system. Access to police applications is refused. Applications to content management are permitted. Storage takes place in a data bank for each user name and for a specific user group, such as e.g. “transport operators”, “diplomats”, etc.

[0079] Intranet

[0080] The user has a personalized access and generally has the function of a police officer or magistrate. Access to police and other applications is partly to fully allowed. Storage takes place in data bank per user name and for one or more specific user groups, such as e.g. “police officer”, “office manager”, etc. As the said user circle normally has also direct access to the file system (office communication, etc.), a profile is also linked with the user profile of the operating system (NT, LDAP, etc.).

[0081] The data security referred to hereinbefore under c) is produced by means of an encryption mechanism, which encrypts and decrypts all data transmitted and received via an active session. A session begins with the logging in of the user and ends as soon as a user has logged off or has not been active for a clearly defined time, e.g. 30 minutes. Encryption takes place by means of a symmetrical procedure and for this purpose both sides require an identical key. The latter is produced as described under a) and is only valid for one session.

[0082] In conjunction with the data integrity referred to under d), a distinction must be made between transfer of HTML/WML data and E-mails. In the former case data integrity security takes place by encrypting the transmitted data with an individual symmetrical key for each session. In the latter case security is provided in two steps. Firstly the transmitted data are encrypted as in the first case and secondly each E-mail receives a sender signature.

[0083] Hereinafter and with reference to FIG. 3 further details will be given on the functional systematics of the intelligent, dynamically implemented portal B. It is a dynamic portal, because the contents of the portal are displayed as a function of the external context, which comprises the following elements:

[0084] date, time

[0085] user

[0086] special, police-relevant events.

[0087] The portal B assumes the function of an intermediary of the user, bound to the portal B by one of the aforementioned access channels and the downstream information systems of the police. The intelligent portal B has different tasks, which are implemented by means of different engines. To ensure that users are supplied by said engines with the desired data important and necessary for them, in an upstream layer in a device 54 there is an authentication or personalization for the purpose of authenticating and identifying a user. Following this in an engine layer there is a subscription engine 56, a filter engine 58, an information repository engine 60, an application repository engine 62 and an office communication repository engine 64, whose functions were described hereinbefore. The filter engine and subscription engine represent intelligent agents. The engines for the purpose of fulfilling their engine information area functions, communicate via fixed, specified interfaces with different information processing systems operating in the background.

[0088] The engine layer is located on a layer with a not shown administration device for administering users, engine configuration and administering upstream and downstream layers.

[0089] The downstream systems C incorporate two external data banks 36 a, 36 b of a private and a public organization, a local application device 42, a local office communication system 44, a local data warehouse 46, a local media data bank 43 and local data banks 45.

[0090] The components shown in FIG. 3 completely cover the different police task fields. Access to the different applications and value-added services, whereof one is shown and given the reference numeral 66, through the portal B is controlled by the association of user and user group rights. Thus, each officer is provided with those applications which he requires for fulfilling his specific functions. As a result of the integration of these components in the information service system, they are displayed in their sense context. This facilitates the linking of the existing data with information.

[0091] On the basis of the enquiry, a request broker 68 associates it with the correct engine and after running the enquiry ensures that the information obtained is transmitted back to the correct user. By means of an output engine 70 the user is given the possibility of obtaining information objects via different communication channels in different formats. There is also an interface integrator 67.

[0092] Portal B permits the implementation of the idea of the operative work of the police. By means of a standardized access, namely the portal, the different application devices (legacy systems) of the police are rendered accessible and interlinked and consequently become an indirect part of the portal. It is important to produce the context from the data of the existing application devices, in order to give a new information quality and therefore generate the additional service necessary for the police. The necessary information is displayed in context making the police better able to fulfil their functions and enabling strategic aims to be more logically fulfilled.

[0093] Besides the integration of existing application devices on the basis of the above-described portal architecture, the invention also includes the identification, implementation and integration of future application devices in the portal.

[0094] After production on the basis of the presently described architecture, new application devices can be made available in a simple, standardized manner and linked with existing information systems. Thus, the police can be assisted in those areas where, as a result of lack of instruments, existing potentials cannot be completely exhausted at present. For example, it is possible to integrate and integrative controlling, risk management instruments or training and knowledge application devices.

[0095] As a result of the integrative aspect of the portal, information from different applications is interlinked and made available, as needed, by users. It is e.g. possible to gather use recommendations and handling alternatives from present case data and filed information on past cases. Another example would be the information side provided in geographically regionalized and user group-related manner. Thus, an officer is acquainted with existing, regional, police-relevant events. For example, he requires search information or local events and activities. These so-called value-added services are created by intelligent linking and representation of given data values in the form of aggregated and selected information for the police.

[0096] The visual essence of the information service system can consist of a starting page containing links to the integrated applications and value-added services. The links are grouped in integrated applications, value-added services and personal applications. The personal applications include e.g. E-mail, use planning and local events, but also personal search agents resulting both from integrated applications and value-added services. These are the most frequently utilized portal components and which must therefore be made the most easily available.

[0097] The intelligent portal links existing or future police applications and creates additional value from given data as a result of a common surface and integrated services. The individual components can be existing applications, which could also exist independently, such as E-mail or operative information system, or future applications, which are then integrated in the portal.

[0098] The integration of applications from the following areas is possible for comprehensively assisting police tasks.

[0099] Target-oriented Control

[0100] This application case covers all evaluations of operative data for detailed use planning, including (a) the determination of information, (b) linking information, (c) geographical representation of information (regional evaluation of facts) and (d) making available information for controlling and risk management.

[0101] Operative Information and Control System

[0102] This application case covers the provision of control information, which can be subdivided into the following:

[0103] (a) Internal result, e.g. debit note

[0104] (b) External result, e.g. clearing up rate, subjective feeling of security, recurrence figures

[0105] (c) Processes, e.g. ratio of value-creating to administrative activities, average clearing up period, ratio of arrests to convictions

[0106] (d) Organization, e.g. sick rate, attended training programs, number of implemented improvements.

[0107] The innovation consists in the availability and attainability of information. At present such information is determined manually and then sent in E-mail form to the party in question and other persons. Integration by means of the information service system portal means that the relevant information is made available to the given parties by subscription or search and using the portal.

[0108] Competency

[0109] The “competency” application case relates to training measures which can be offered via the portal. As a result of the technology used the office is able, as required, to attend training offers on-line in his working environment. These training offers include interactive learning programs passing from electronic reference works, via simple dialogue-controlled training and finally extending to media training.

[0110] Administrative Assistance

[0111] Administrative assistance by the portal covers all tasks linked with cases and also all personal, administrative activities, which are necessary, but take up a large amount of time. As a result of the use of the portal there is an integration of available information resources, so that as a result of the integration an efficiency increase is obtained. An example is the direct obtaining of information at the location of the event, followed by the obtaining of further specific information and finally the administration of the information in the form of individual reports. In the specific example the portal directly renders available all the necessary information and this can be further processed at another location without previously acquiring the information again. At present such information is polled by radio and therefore an additional officer. Subsequently the information is noted and extended by more specific information. The latter is passed by radio to another officer (e.g. team leader) and noted. On adding further information, collation takes place and in the least favourable case the initial information enquiry is repeated.

[0112] Each officer also has personal administrative tasks and these can be simplified by different applications integrated into the portal. Through the personalization of information relevant to the officer, he can be automatically supplied therewith. There is no need for the officer to personally obtain this information. For example, an officer can be automatically supplied with new training offers for his special field.

[0113] Value-added Services

[0114] These services are those allowing information polling and the acquisition of actual data. For example, actual data can be acquired and transmitted in situ, i.e. in the office or at the location of the event. Aggregation categorization and evaluation of the data are automated. The evaluations obtained in automated form are then supplied to the particular officer as a function of the personalization mechanisms. This process can take place by the provision of the value-added just-in-time service. Up to now the procedure has required multiple manual activity and has taken 24 or more hours.

[0115] Hereinafter details are given of a possible application of the information service system according to the invention. This application relates to the integration of the information service system into the everyday activities of a police officer equipped with a terminal in the form of a WAP-capable device. It is also used for illustrating how the officer is provided with an added value by the portal as a result of the integration of information systems and which he cannot have without said portal.

[0116] At the start of his shift in the first district of his home town Schdnstadt Peter Sicher and his colleague Zabel travel with a service vehicle to the district allocated to them via the information service system.

[0117] (a) Sicher switches on the WAP-capable device installed in the vehicle. On reaching the target area, they receive the information that the duty roster has changed through the loss of two colleagues and they are to be used in a different district. As the two do not have information on this district, they call up the value-added “risk management” service of the information service system, where both learn that over the last few months in this quiet area increasing numbers of burglaries have occurred. Although a precise demarcation of the area has been possible, up to now no suspects have been found. Sicher and Zabel decide to show a greater presence in the area in question.

[0118] (b) In his personal subscription Sicher acquires the information that in four weeks a training course in his special field of “procurement crime” will be available. He immediately applies for it and is automatically informed that a place has been reserved for him. Automatically documents are sent to his electronic post box and the training course is noted in the use planning system. His team leader also receives an electronic communication immediately confirming this in the office.

[0119] (c) On entering a side street Zabel notes that a vehicle has been unlawfully parked on the pavement. On approaching more closely he finds that the vehicle is not locked. By means of the information service system portal B, he polls the INPOL data bank 36 c the registration details of the vehicle (cf. FIG. 4), but no messages are provided. The not shown filter engine supplies him with the message that the vehicle owner is being sought in the EUROPOL data bank 36 d. However, there is no entry in the INPOL data bank 36 c. Zabel records the location of the vehicle and passes the information back to the office DS. By radio contact he contacts the team leader who, in the meantime has in his portal B the established information and also the EUROPOL information. The team leader makes all the necessary arrangements and Sicher and Zabel are to park their vehicle in the vicinity and wait for further instructions.

[0120] At the end of the day the service manager DL receives an evaluation of all incidents of the day in question by means of the local device 42. On the basis of this information he decides about necessary adaptations of the duty roster for the following day. Duty roster adaptations are secured and the police offers are automatically informed of the changes.

[0121] (d) Back in the office DS, Sicher and Zabel make the necessary reports by means of the local office communication system 44. They make use of the entries recorded during the day. Most of the work has already been dealt with as these are usually standard procedures. The cases encoded in situ are already available in printed-out form in their filing compartments.

[0122] Four applications of the information service system were described above. Each application case reveals a special function only available to a limited extent or not available in the police service at present:

[0123] (a) Direct information on a data evaluation

[0124] (b) Direct information on personal interests/requests

[0125] (c) Intelligent integration of different systems and integration of information for further processing

[0126] (d) Further use of mobile-acquired data for efficient processing of standard procedures.

[0127]FIG. 4 shows the information flows between a user, namely Sicher and components of an information service system corresponding to the previously described application case. The reference numerals have the following significance:

[0128]101 Authentication

[0129]102 a Personalization
